Sci*lebrity of the Day

Posted by Thomas Cadolino on

William David Coolidge (Born on October 23, 1873) was an American physicist, engineer and physical chemist whose improvement of tungsten filaments (U.S. patent No.1,082,933, issued 30 Dec 1913) was essential in the development of the modern incandescent lamp bulb and the X-ray tube. Coolidge's X-ray tube (1916, U.S. patent No. 1,203,495) completely revolutionized the generation of X-rays and remains to this day the model upon which all X-ray tubes for medical applications are patterned. He worked on many other devices such as high-quality magnetic steel, improved ventilating fans, and the electric blanket. During World War II he contributed research to projects involving radar and radar countermeasures. He was awarded 83 patents during his lifetime.
